Architect and maintain event-driven systems using Kafka / RabbitMQ
Design clean domain-driven services (inspection flows, reports, billing, notifications)
Work with PostgreSQL (schema design, optimization, migrations)
Improve system reliability, observability, and performance
Participate in architectural decisions (modular monolith vs microservices boundaries)
Collaborate closely with frontend, QA, and AI teams
Write clean, testable, production-ready code
Help improve CI/CD and deployment pipelines (AWS environment)
